Hallett Cove Conservation Park on Adelaide's southern coast, is one of Australia's most outstanding geological sites, recording an Australian ice age some 280 million years ago.
About 500 million years ago the region was squeezed by massive earth movements which folded rocks and formed them into mountain ranges. Such folds are clearly seen at the southern foot of Black Cliff and along the wave cut platform to the north. Four main periods of the geological history of Hallett Cove are described along the park's interpretative walking trails.
We plan to return and get some shots showing some of these formations when the grandchildren are at an age they can appreciate what they are viewing.
